When zoomed in, the pop star's foot includes the numbers "8418," which is the badge number worn by the Saturday Night Live comedian's late father, New York City firefighter Scott Davidson, who died in 2001 during the Twin Tower attacks. The 24-year-old comedian also has same numbers inked on his left forearm, which he's had for quite some time now.

Mesa recalled an instance last month when Davidson called about covering up some ink. Notably, a tattoo of his ex-girlfriend, Cazzie David's, face.

"I did a huge coverup [adding a forest of trees]," Mesa explained. "After we were done, I told Pete, ‘Hey, dude, let’s just stop with the girlfriend tats until after [Grande’s] your wife'….Relationships come and go, and Pete is a really young man. [But] I think that went in one ear and out the other.”

Davidson definitely didn't take the advice, as he got himself inked with two pieces dedicated to the pop star just two weeks later -- one of her initials on his thumb and another of the black bunny mask Grande wore on the cover of her Dangerous Woman album.

Davidson, however, told Jimmy Fallon this month that being engaged to Grande feels like he "won a contest." Watch the video below to hear his comments.
